Watch List notes:

Maurice Tiberius. 582-602. Æ Follis (31.6 mm, 12.65 g, 1 h). Cyzicus, Year 10 = 591/592. O N MAVRIC TIbЄR PP A (or similar), crowned and cuirassed bust facing, wearing consular robes, holding mappa and eagle-tipped scepter / Large M, ANNO to left, cross above, X to right, A below, KYZ in exe. SBV 518; DOC 127a. aVF, red patina. 

This series is typically crude, but the blundered obverse legend and cartoonish portrait make me think this may be a barbarous imitation. The reverse style seems fine.
